i'm pleased to announce release -v9 of the CFS scheduler patchset. (The
main goal of CFS is to implement "desktop scheduling" with as high
quality as technically possible.)

The CFS patch against v2.6.21.1 (or against v2.6.20.10) can be
downloaded from the usual place:

-v9 is a small fixes-only release:

6 files changed, 34 insertions(+), 29 deletions(-)

it includes small fixlets, the most notable of which is the 64-bit SMP
balancing fix from Balbir Singh. Things are clearly calming down and
there's been no report of interactivity regression against -v8 so far,
which is certainly promising. So please try to break -v9 :-)

Changes since -v8:

- SMP balancing fix for powerpc/64-bit. (Balbir Singh)

- build warning fix and microoptimization: sched_find_first_bit() only
needs to cover 100 priority levels. (Mike Galbraith)

- fix long initial delay in tasks reniced in a positive direction.
(reported by Al Boldi)

- fix missing syscall_table.S entry for sys_sched_yield_to.
(noticed by Vegard Nossum)

- small tweaks to the /proc/sched_debug output

As usual, any sort of feedback, bugreport, fix and suggestion is more
than welcome,

Ingo
